2004 Deville Northstar using oil.
I have a 2004 Deville with the Northstar engine. Over the last few oil changes it seems to be using oil. Have had to add about 2 quarts during the normal 3000 mile oil change cycle. No leaks. If it is burning oil what is the standard engine work to repair?
Is it smoking white/blue- tint from tail pipe?
no smoking that I can see. No visible tint on tail pipes.
Check the area near the oil pressure sending switch. They're prone to leakage and often times will not drip on the ground. A guy at work has a '97 DeVille that drove him nuts trying to find out where his oil was going. Turned out that's what it was. HTH. -Jim
